摘要： A processing apparatus is provided that includes an encoder configured to encode current frames of video data using previously encoded reference frames and perform motion searches within a search window about each of a plurality of co-located portions of a reference frame. The processing apparatus also includes a processor configured to determine, prior to performing the motion searches, which locations of the reference frame to reload the search window according to a threshold number of search window reloads using predicted motions of portions of the reference frame corresponding to each of the locations. The processor is also configured to cause the encoder to reload the search window at the determined locations of the reference frame and, for each of the remaining locations of the reference frame, slide the search window in a first direction indicated by the location of the next co-located portion of the reference frame.

摘要： A server offloads graphics effects processing to a client device with graphics processing resources by determining a modification to a graphics effects operation, generating a portion of a rendered video stream using the modification to the graphics effects operation, and providing an encoded representation of the portion of the rendered video stream to the client device, along with metadata representing the modification implemented. The client device decodes the encoded representation to recover the portion of the rendered video stream and selectively performs a graphics effects operation on the recovered portion to at least partially revert the resulting graphics effects for the portion to the intended effects without the modification implemented by the server.

摘要： Various codecs and methods of using the same are disclosed. In one aspect, a method of processing video data is provided that includes encoding or decoding the video data with a codec in aggressive deployment and correcting one or more errors in the encoding or decoding wherein the error correction includes re-encoding or re-decoding the video data in a non-aggressive deployment or generating a skip picture.

摘要： Systems, methods and apparatuses of processing data of a VR system are disclosed that comprise receiving tracking information which includes at least one of user position information and eye gaze point information. One or more processors may be used to predict, based on the user tracking information, a user viewpoint of a next frame of a sequence of frames of video data to be displayed. Using the prediction, a portion of the next frame of video data to be displayed is rendered at an estimated location in the next frame. A corresponding matching portion in a previously encoded frame is determined based on the estimated location of the portion in the next frame and the portion of the next frame of video data is encoded.

摘要： Adaptive decoder-drive encoder reconfiguration techniques are described. In one example, techniques include detecting an operational condition at a consumer using a sensor, the consumer receiving a communication of digital content from an encoder; generating an adaptation instruction by the decoder based on the detecting; transmitting the adaptation instruction by the decoder for receipt by the encoder; and receiving an adapted communication of the digital content generated by the encoder, the adapted communication caused by reconfiguration of the encoder based on the adaptation instruction received from the decoder.

摘要： A processing system selectively renders pixels or blocks of pixels of an image and leaves some pixels or blocks of pixels unrendered to conserve resources. The processing system generates a motion vector field to identify regions of an image having moving areas. The processing system uses a rendering processor to identify as regions of interest those units having little to no motion, based on the motion vector field, and a large amount of edge activity, and to minimize the probability of unrendered pixels, or “holes”, in these regions. To avoid noticeable patterns, the rendering processor applies a probability map to determine the possible locations of holes, assigning to each unit a probability indicating the percentage of pixels within the unit that will be holes, and assigning a lower probability to units identified as regions of interest.

摘要： A processing device includes an automated overclocking system and a processor. The automated overclocking system is data-driven and includes an inference engine that executes a machine learning model configured to generate a first output based on a current configuration of the processing device. The first output includes a first set of overclocking parameters. The processor is configured to adjust one or more operating characteristics of at least one component of the processing device based on the first set of overclocking parameters.

摘要： The present disclosure is directed a system and method for exploiting camera and depth information associated with rendered video frames, such as those rendered by a server operating as part of a cloud gaming service, to more efficiently encode the rendered video frames for transmission over a network. The method and system of the present disclosure can be used in a server operating in a cloud gaming service to improve, for example, the amount of latency, downstream bandwidth, and/or computational processing power associated with playing a video game over its service. The method and system of the present disclosure can be further used in other applications where camera and depth information of a rendered or captured video frame is available.
